HelloPharmacist Scorecard of Fenugreek & Fennel by TerraVita
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
This liquid contains two active ingredients: fennel glycerite liquid extract and fenugreek glycerite liquid extract—a total of 2 active ingredients. Both come as extracts dissolved in glycerin, a sweet, clear liquid that acts as a preservative and makes the product easy to take by mouth.
Fennel has long been used in cooking and traditional medicine, traditionally valued for digestive comfort and other purposes. Fenugreek seed, also common in cooking (especially Indian cuisine), has been studied for blood sugar and sexual function.
The glycerin vehicle is a standard inactive ingredient used in herbal liquid extracts.
Does it work?
Moderate evidence
The facts show fennel is possibly effective for dysmenorrhea (painful menstrual cramps). Evidence for fennel's use in bronchitis, anxiety, nocturnal bedwetting (enuresis), and cholera is insufficient to rate.
Fenugreek is possibly effective for sexual dysfunction and dysmenorrhea, and for diabetes support—clinical studies show it can reduce fasting blood sugar and post-meal glucose levels in people with type 2 diabetes. Beyond those uses, the evidence on file is not established.
How safe is it?
Well-documented data
Both fennel and fenugreek are generally well tolerated in food amounts, though concentrated supplements deserve more caution. The most common side effects from fenugreek taken orally are abdominal pain, bloating, diarrhea, indigestion, gas, and nausea.
Fennel may cause gastrointestinal discomfort, sun sensitivity, and allergic reactions; rarely, it has been linked to seizures. Both ingredients carry a rare risk of severe allergic reactions including throat swelling, bronchospasm, and shock—stop immediately if you experience wheezing, difficulty breathing, or facial swelling.
Fennel is rated possibly unsafe in pregnancy due to limited safety data and hormone-like effects, and possibly unsafe while breastfeeding in medicinal doses. Fenugreek is rated likely unsafe in pregnancy and possibly safe while breastfeeding.
If you're pregnant or nursing, talk with your doctor or pharmacist before taking this product.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you take any blood thinners or antiplatelet drugs (including warfarin, clopidogrel, and aspirin), diabetes medications, contraceptive pills, hormone replacement therapy, tamoxifen, theophylline, metoprolol, ciprofloxacin, phenytoin, or sildenafil. Both fennel and fenugreek carry moderate-severity interactions with several of these drug types.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This blend may appeal to people interested in digestive support or traditional women's health uses, but it carries multiple documented interactions with blood thinners, diabetes medications, hormonal drugs, and several others. If you take any prescription medications—especially for blood clotting, blood sugar, or heart conditions—check them against the interaction tool on this page or discuss this product with your pharmacist or doctor before starting.
Pregnant people should avoid it; nursing people should confirm safety with their provider first.

Fenugreek & Fennel by TerraVita Drug Interactions
HelloPharmacist Interaction Report
TerraVita's Fenugreek & Fennel is a two-ingredient liquid blend through its fennel and fenugreek content.
The most serious interaction involves anticoagulant and antiplatelet drugs (blood thinners like warfarin and clopidogrel), where both ingredients may increase bleeding risk or alter how these medications work—fennel through potential antiplatelet effects and fenugreek through additive blood-thinning activity.
Read the full breakdown — every affected drug type, severity by severity
Fennel also interacts with contraceptive medications, hormone replacement therapy, and tamoxifen (a breast cancer drug) because some of its compounds mimic estrogen, potentially reducing the effectiveness of these treatments. It may also raise levels of certain medications metabolized by the liver (CYP3A4 substrates) and decrease the effectiveness of the antibiotic ciprofloxacin.
Fenugreek carries additional interactions: it may intensify the blood-sugar-lowering effect of diabetes medications, reduce how well theophylline (an asthma and COPD drug) works, lower blood pressure when combined with metoprolol, decrease phenytoin (an anti-seizure drug) levels, and reduce sildenafil (Viagra) effectiveness. It may also interfere with how clopidogrel converts to its active form.
Additionally, no interactions are documented for glycerin, the inactive ingredient. Altogether, these interactions span 971 individual medications.

For each ingredient in Fenugreek & Fennel with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Fenugreek & Fennel Glycerite Liquid Extract
Anticoagulant/Antiplatelet Drugs
Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.
Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels .
Antidiabetes Drugs
Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.
Clinical research shows that fenugreek seed can reduce fasting blood glucose and 2-hour postprandial glucose levels in adults with type 2 diabetes.
Clopidogrel (Plavix)
Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.
Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11%.
Metoprolol (Toprol)
Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.
Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg.
Phenytoin (Dilantin)
Theoretically, fenugreek might decrease plasma levels of phenytoin.
Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance. So far, this interaction has not been reported in humans.
Sildenafil (Viagra)
Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.
Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively. So far, this interaction has not been reported in humans.
Theophylline
Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.
Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22%.
Warfarin (Coumadin)
Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).
Some fenugreek constituents have antiplatelet effects, although these might not be present in concentrations that are clinically significant. In one case report, a patient taking warfarin experienced an increased INR when starting to take fenugreek in combination with boldo.
Antihypertensive Drugs
Fenugreek may also have an additive effect on blood pressure-lowering medications. Studies on animals have shown that fenugreek seed can decrease both systolic and diastolic blood pressure by up to 22% when combined with metoprolol. Therefore, it is essential to monitor your blood pressure regularly if you are taking fenugreek and metoprolol together or any other antihypertensive drugs.
